Disc brake conversion on a Dana 25 or 27 Willys Jeep front axle

This is a video showing the disc brake conversion I did on my 1961 Willys 4x4 station wagon. This is the Dana 25 front axle. Here are the parts you need... 1976-1977 Jeep CJ rotors (the older thicker ones, 1 1/8" thick) 1973-1991 GM 1/2 ton 4x4 front brake backing plates 1971-1978 GM 1/2 ton 4x4 front brake calipers, lines, pads Dorman studs, PN 610106 Search Google for the write-ups. Everything bolts on, but you do have to grind some material off the knuckle for the calipers to clear. You also need to use different fill plugs for the knuckle; I used electrical conduit plugs. You also need a 1/8" bearing spacer, or remove 1/8" of material from the hub where it faces the rotor, or remove 1/8" material from the inner brake pad. If you are using the factory master cylinder, as am I, you need to remove the residual pressure valve. This valve maintains pressure in the brake line plumbing for the drum brakes, and will cause the disc brakes to drag. I use a 10 pound Wilwood residual pressure valve in-line to the rear drum brakes, and a 2 pound Wilwood RPV to the front disc brakes.
